Summary: `CFBridgingRelease` and `__bridge_transfer` which I'll model later, transfer the memory model from manual memory ref count to ARC (automatic ref count), so to avoid false positives this needs to be modelled. We can simply remove the Allocated attribute from the state, which means we won't try to track that memory anymore.

Summary:
This models all the Create and Copy functions from CoreGraphics, examples in the tests.
These functions all allocate memory that needs to be manually released.
The modelling of the release functions will happen in a following diff. Until then, we have some false positives in the tests.
This check is currently in biabduction, and we aim to move it to Pulse.
